8312148 ÷ 77 
The aim is to understand the frequency of 77 in 8312148.

Going ahead to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 77

On to step 2:
If we divide 83 by 77, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 83 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 77

Moving on to step 3:
77 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 77

Moving on to step 4:
77 can be fit into 612 7 times, resulting in a remainder of 73.
The next digit of our result is 7. 
Result so far: 107.0
If we take 539 away from 612, we end up with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 77

Let's proceed to step 5:
731 divided by 77 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 1079.0
Subtracting 693 from 731 leaves us with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 77

Moving on to step 6:
77 goes into 384 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 10794.0
The remainder is 76 after subtracting 308 from 384.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 77

Advancing to step 7:
If we divide 768 by 77, we get 9 and a remainder of 75.
The next digit of our result is 9. 
Result so far: 107949.0
Subtract 693 from 768 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
If we divide 750 by 77, we get 9 and a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 107949.9
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 77, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 107949.97
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 107949.974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 107949.974
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 77, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 107949.97402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
77 can be fit into 460 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 107949.974025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 77 fits into 750 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 107949.9740259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 15:
570 divided by 77 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 107949.97402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 107949.97402597 with a remaining 3.1e-08.
